Fix display_id usage in the trophy box.

The trophy box was using the review request's display_id to compute whether to
display, but was using id for the text displayed on the page.

Fixes bug 3037.
Add back a parameter for Bitbucket unit tests.

The expected_http_called parameter accidentally got removed from the
wrong class's function. It was meant to be removed from Beanstalk, not
Bitbucket.
